Considering the following and wonder what the net gross hp gain would be on my 97 m.

JR CAI 10 HP
Catback exhaust 4HP
Sludge (polish) intake manifold 8HP
Timing advance 14 ?

New to miatas so any feedback would be appreciated

 

8.46 hps gained. Can you feel the powa and throttle response!

 

Hope that helps

 

Not sure if trolling or really that stupid.

 

Came from building corvettes so no not really that stupid. Clarifications. 14 on timing was degrees. Sludging a manifold is polishing the inside. All the HP gains noted were from vendor sites. Obviously take with a grain of salt.

 

To have genuine numbers, you have to do it this way:
dyno your car stock, then dyno it after bolting on each part, 1 at a time. You cannot go by advertised numbers. However, if you do buy all those parts, you will have wasted your money and could have put it towards a turbo. You will only be happy if you add boost.

What we're saying is you're are never going to make any power N/A. Hence you logged on to MIATATURBO. Posting your N/A mods is a total joke here. Maybe try Miata.net.

 

Might just take advantage of my vette experience and put an ls1 in it

 

Since when is polishing "sludging?" are you talking about extrude hone? What is a polished intake manifold even mean anyway? The intake isn't supposed to be polished. that's the exhaust side smarty pants.

And if you paid attention to my post, I did give you a real power assessment. Maybe about 5hp.

 

Ls1 swap? Do it! No *****...

 

Thanks 3gen. I didnt realize the limits of the post here to just FI. Won't make that mistake again. Got some real egos on this site.

 

www.miata.net

Go there. All your N/A info awaits.

 

It's not so much egos, as it is www.miataturbo.net. Hell, I have a supercharger and I still get flack but I don't take it personally.

Anyways, if you're staying N/A you're not at the right site. You'll find WAY more information and basic Miata N/A knowledge at miata.net forums.


Now on a serious note, if it's a 1.8L and you do intake, exhaust (with headers), timing bump and port/polish your intake manifold you'll be lucky to make 15hp extra. Miatas don't respond as well to bolt ons like Honduh motors do.

 

CAI don't really add any power, cat-back may net you 3-4 hp, add a header and hi-flow cat and you might net a total of 6-8

Increase in timing helps the mid-range more than anything, totally worth running 93 for it too.

Best bet for n/a power is swap in a 99-00 engine, MSM intake cam, JDM/EUDM intake manifold(aka square-top), standard I/H/E and you should make 140-150rwhp on a good day


Sounds like an awesome plan!

http://www.v8miata.net/ will get you there.

 

This is a fantastic idea.
Smartest thing you said thus far.
If you're also smart enough to pull it off, you'll have a helluva car and we will respect you

If you want any noticeable power at all, you'll realize real quick at how patheticly slow an n/a miata is in a straight line.
Unless you're planning on road racing forget n/a.

 

Well even though I opened up the wrong discussion topic it's always good to get both sides. And I'll go one of three ways SC, TB, or v8. Other way just isn't worth messing with. I ended up with the miata over another vette because I really liked the way it handles. Rally fun car to drive. Problem is from the factory it's gutless horsepower wise.

 

NAh, this forum gives less crappy info about IHE and additive fictive numbers about electric superchargers and whatnot...

There is info and knowledge about real N/A builds in here is you search.

Get the flow up in the head, increase the compression and tune the cams, intake and header to the rev range you want to run.
There is nothing special about it, except that you don't start at 50 bhp/liter and that the ports are designed for boosted applications (i.e you have to know what to do to get results).

 

SC: Super Charged
V8: Vee Eight
TB: Tur-Bo?

 

Deep down, all of us want an all-aluminum Gen IV LS motor. It is, hands down, the best naturally aspirated mod you can do.

 

No simple bolt-ons here, but plenty of n/a goodness. And the sound...
